AUTOv/-OBLE SIGNAL. f

that the following is a full, clear, and enact description thereof.` f

The invention relates to automobile signals. lt comprises a casing partitioned into two compartments, a plate in one compartment having the word Stop cut therethru,

an'electric lamp for illuminating` the plate and making the word 'StoiLf `visible lat night, andv plates pivoted in the other compartment having the words Left `and Right cutv therein thru which light-is emitted from a lamp, the lamps being'adapty ed to be-illuminated when the plates are thrown to operative signalling positions.

A primary object of the invention is the provision of signals plainly visible in the day time, the plates being conveniently disposed to signal to the operators of following cars, and which are illuminated at night time, the electric lamps being` lighted simultaneously 'with themovemen't ofthe plates to visible position. The plates occupy but little space and the Stop sign may be conveniently revealed either alone or simultaneously with a Left7 and Right sign.

An important 'obj ect is the convenience of operation of the device, the Stop signal being thrown on alone by depression of the brake pedal or simultaneously with a Left or Right signal by the convenient manipulation of a lever ydisposed within the reach of the driver. Springs are provided for automatically restoring the plates to normal inoperative positions, restoration of plates to these positions being concomitant with a breaking of the electric circuits so that the lamps are extinguished.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangen'ient of parts substantially as hereinafter described and more particularly defined by the `appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying` drawing, l have illustrated one complete example of the phys- .l5 and 16.

Shafts 2l and 22 in a ysimilar lmanner, carry plates29 and 30 respectively, for signalling left and.right respectively. Pulley 3l is rigid with shaft 17 and at a point on the periphery'thereof,

cable 82 is secured, .which ermendsv down 'y wardly over pulley 83 and' rearwardly thru pi anopening in ra frame 34; supported pivotally at 35, the cable having a stop 3G thereon immediately adjacent the frame. Connected tothe cable is a spring 87 secured Vto brake lever 38.

lf the stop plate 28 reaches its operative position before brake lever 38 reaches its lowermost position, spring 37 will. expand.

from battery49 normal inoperative position, springe? se- 1in y l On the restoration of brake lever 38 to zits leads over sheave 53 to arm 54, pivoted at and having handle 56 rigid therewith.

Movinghandle 56 to the lett, lifts arm 5' and brings stop 52 againstrame 34, tensioning spring 57 secured to the traine, and moving kthe raineagainst stop 36, so that cables 50 and 32 are tensioned. rlliis results in moving pulleys 31 and 49, and movingplates 28 and 29 downwardly, displaying"stop and let7 signals. Arm 23 is thiis brought against Contact plate 25 and current is directed from battery/139 through leads 40 and 58, lamp 14, lead 59, Contact plate 25, oontaet arm 23, lead 60 and lead. 43. Thus lamps 13 and 14 are simultaneously illumi' nated. The release of lever 56 permits plates 28 and 29 to return to their normal elevated inoperative positions under the influence of springs 47, spring 57 restoring iframe 34 to its normal position. When lever 56 is moved to the right, Cable 61, secured to arm 62, rigid with the lere:v and extending over sheave 63, is tensioned, thus bringing stop 64 on Cable 61 against frame 34.

its cable 61 is secured to pulley `65, Which is rigid With shaft 22, the shaft is rotated .on the tensioning oi' the cable, and right plate 30 is elevated, Contact arm 34 being brought .against Contact plate and closing an electric Circuit illuminating lamp 14. 1n this operation, frame 34 is brought against stop 36, and stop plate 23 is also moved to signalling position, lampl 13 being also illnininated. p

lt is therefore apparent that by the mere depression of the brake pedal, the stop plate will be made visible and lamp '13 illuminated, and that by the proper manipulation ot the handle 56, the lett or right plates may be moved to visible position, stop plate 26 being also operated and lamps 13 and 14 illuminated.

l olaimy The Combination ot a housing, a partition dividing said. housing into tivo compartments, a stop plate pivoted in one ot said oompartn'ients, left, and right plates pivoted in the other of said compartments, an eleotrie lamp in each of said compartments, means for moving the stop plate to visible position and illuminating one ot' said lamps to make said stop lplate visible, and means for moving either oit the left and right plates to visible position, and simultaneously ino-ving said stop plate to visible position and illinninating both ot said eleetrie lamps.

lnl testimony that I claim the foregoing` l have hereunto set my hand at North Chi caefo, in the county o1c Lahe and State of illinois.
